ENHANCED PERFORMANCE OF ALCOHOL FUELED ENGINE DURING COLD CONDITIONS Abstract of the Disclosure Apparatus and method are described for enhancing performance of an alcohol fueled engine during cold conditions, with such enhancement being particularly effected by generation of ether to assist cold operation including starting and/or to achieve reduced emissions during cold running. Dimethyl ether is generated by catalytic dehydration of vaporized methanol using a catalyst, preferably fluorinated alumina. Apparatus is disclosed for generating dimethyl ether on board as needed for immediate mixing with combustion air and methanol and/or for storage to enable later mixing of the dimethyl ether with combustion air and methanol to effect subsequent cold starts and/or cold running operations.
